Orbital Sciences Corporation Kerbal Space Program Erdbeobachtung : Diese Satelliten machen Google Earth überflüssig - Nachrichten Wissenschaft - Weltraum Die Firma Planet Labs will mit 28 Weltraumkameras scharfe Bilder von der ganzen Erdoberfläche liefern und diese mindestens einmal pro Woche aktualisieren. Google Earth wird da ganz schön alt aussehen. Von Rainer Kurlemann In diesen Tagen beginnen die Astronauten auf der "Internationalen Raumstation" (ISS) mit einem besonderen Arbeitseinsatz. Die Mikro-Satelliten sind auf das Notwendigste beschränkt. Dennoch besitzen sie das Potenzial, Google Earth abzulösen. Mehrmals täglich neue Luftbilder Von manchen Regionen wird es dann mehrmals täglich neue Luftbilder geben, die übrigen sollen wenigstens einmal pro Woche aktualisiert werden. Der Initiator dieses Satellitenschwarms ist eine private Firma: Planet Labs in San Francisco, gegründet vor vier Jahren von drei Technikfreaks, die früher bei der US-Weltraumagentur Nasa gearbeitet haben. Die Ingenieure haben sich Mobilfunk und Handytechnik zum Vorbild genommen und alle Bauteile miniaturisiert. Menschen lassen sich nicht identifizieren
Minecraft Skybox Imaging - Products Fastest Access to the Skybox Constellation Your fastest access point to the Skybox constellation is a SkyNode – a compact system consisting of a 2.4 meter satellite communications antenna and two racks of electronics. We package this small-footprint system with our premier platform applications, which allow you to create orders, schedule collections, monitor the constellation, and produce and archive imagery. You'll go from downlink to accurate, relevant imagery and video in as little as 20 minutes. Uninterrupted Access We understand the importance of reliable, dependable access when you need it. Built to Scale SkyNode software updates are designed to be seamless and frequent. Flexible Access Plans Whether you need minutes of access per month or complete global satellite capacity, we'll work with you to select the Access Plan that meets your mission needs.
Webcomics Plasma Jet Driven Magneto-Inertial Fusion is an Inertial Confinement Fusion (ICF)-Magnetic Confinement Fusion (MCF) hybrid approach TweetHuman hopes of reaching stars other than the Sun are currently limited by the maturity of advanced propulsion technologies. One of the few candidate propulsion systems for providing interstellar flight capabilities is nuclear fusion. In the past many fusion propulsion concepts have been proposed and some of them even explored in high detail (Project Daedalus), however, as scientific progress in this field has advanced, new fusion concepts have emerged that merit evaluation as potential drivers for interstellar missions. PJMIF involves converging plasma jets that are launched from symmetrically distributed plasma rail-guns (or plasma guns), so as jets come in, they merge and form a plasma liner that compresses the plasmoid target (spheromak or FRC), which reaches fusion conditions at peak compression. Here is a 2011 presentation by USCL corp Very high specific impulses and specific jet powers can be achieved with fairly low jet velocities of a few hundred km/s. 1. 2. 3. 4.
Teachers Daedalus The world's first engineering study of an unmanned spaceship to explore one of the nearer stars was made by a technical group of the British Interplanetary Society between 1973-77. The target selected for the exercise was Barnard's Star, nearly 6 light years distant from Earth. The contributors recognised that the work, based on the technology extrapolated to the beginning of the 21st Century, could represent only a first approximation to the solution of starflight. The results showed it would be a formidable task requiring a massive craft that would dwarf the Saturn V moon rocket, the largest space vehicle yet flown by man. The result was a two stage, nuclear fusion powered vehicle, unmanned and under autonomous operation due to the distances involved, accelerated to 16% of the speed of light, and armed with a variety of probes, sensors, robotic wardens and intelligent decision making computers.
Comics, Quizzes, and Stories - The Oatmeal Inspiration Mars Foundation Inspiration Mars Foundation is an American non-profit organization founded by Dennis Tito which aims to launch a manned mission to flyby Mars in January 2018. [ 2 ] [ 3 ] [ 4 ] [ 5 ] [ 6 ] The foundation claims that space exploration provides a catalyst for growth, national prosperity, knowledge and global leadership. By taking advantage of this window of opportunity, the Inspire Mars Foundation intends to revitalize interest in science, technology, engineering and mathematics ( STEM ) education. Mission [ edit ] Approximate Inspiration Mars Trajectory (not to scale) Artist's Concept of Inspiration Mars Capsule and Hab. Inspiration Mars Periapsis. The planned private, nonprofit mission [ 7 ] is a 501-day free-return mission which will allow the spacecraft to use the smallest possible amount of fuel to get it to Mars and back to Earth. In 2018, the planets will align, offering a unique orbit opportunity to travel to Mars and back to Earth in only 501 days. Mission technical details [ edit ]
